40                                   ALASKAN GLACIER STUDIES
With this general view of the glaciers of the Yakutat Bay region as a preliminary basis for understanding their main characteristics and their behavior since first studied by Russell in 1890 and 1891, we will proceed to the study of the individual glaciers* and then, upon this basis, to a consideration of the features of general interest and their interpretation, including their bearing upon the interpretation of the Pleistocene drift phenomena of North America and Europe. In this study free use will be made of the results of previous work, as well as of the new observations of 1909 and 1910, the purpose being to set forth the phenomena of glaciation in this region in the light of a series of investigations each of which has added something to a story of glacier condition and behavior of more than ordinary interest, and of quite unusual character.
